Horseradish Root Crowns for Planting
 
Plant once. Harvest every year. 
 
Horseradish (Armoracia rusticana) is one of the simplest perennial crops you can grow. Plant a crown, dig roots every fall, replant a few pieces, repeat. It doesn't need much — reasonable soil, reasonable moisture, room to spread.
 
Fresh-grated root produces sharp, volatile heat that fades fast with cooking and disappears entirely in a jar. Growing your own changes that. You grate it when you need it, and it's a different thing entirely.
 
We grow ours in southeast Kansas and sell bare root crowns with active growing points. These have already handled Midwest heat, cold, and variable rainfall — not greenhouse-raised starts.
 
Planting
Plant in spring as soon as soil is workable, or in fall before first hard frost. Set crowns 2–4 inches deep at a 45-degree angle with the top end up. Space 18–24 inches apart. Full sun preferred. Tolerates partial shade. Adapts to most soils but produces best roots in loose, deep ground.
 
Harvest
Dig roots in late fall after the first frost for best flavor, or in early spring before the plant leafs out. Replant a few pieces each time and the patch sustains itself indefinitely.
 
Management
Horseradish is persistent. Once established it will come back from any root piece left in the ground. Plant it where you want it long-term, or manage the bed edges each season. It's not invasive in the aggressive sense — but it doesn't give up a spot easily either.
